The AP3404 with SOT23 MOSFETs ROHS manufactured by Quan Li is a 3-terminal system-on-chip (SoC) with voltage control and over-current/over-temperature protection circuitry. It is designed to protect the power switch from damage due to over-current and over-temperature conditions. The device features a variety of protection features, including over-current protection (OCP), over-temperature protection (OTP), external flag interrupt, auto-retry after over-current, and current limit. The AP3404 is housed in an ultra-mini thin SOT23 packaging, making it suitable for space-constrained applications. It has an operating temperature range of -40°C to +125°C. Its RoHS compliant and it provide the user with reliable performance and efficient power management.
